Rubblizing Concrete Pavements Using Resonant Vibration ...

rubblizing and demolition and recycling. Pavement rubblizing may be defined as a technique that fractures the concrete slab into angular interlocked pieces using a "resonant vibration" machine. Once concrete pavement has been rubblized, an overlay is built on top of the fractured material. This paper

Rubblization for Airfields and Highways Asphalt magazine

Properly rubblizing PCCP results in the complete destruction of any slab action before applying the HMA overlay. For concrete pavements containing steel reinforcement, such as jointed reinforced concrete pavement (JRCP) and continuously reinforced concrete pavement (CRCP), the steel should be ruptured or the concrete-to-steel bond should be broken.
